The Synoptic Carrington map of UVCS/SOHO O VI intensity generated for
the Whole Sun Month campaign (August to September 1996) (Strachan et
al. 1997, in proceedings of the SOHO 5 "The Coronal and Solar Wind
near Minimum Activity", Oslo). The observations were obtained along
the East limb at a heliocentric height of 1.75 solar radii. The map
shows the logarithm of intensities as a function of Carrington
longitude and latitude for almost two solar rotations.  Brighter
regions correspond to the higher intensities; dark, to regions where
the relative intensities are small. e.g., as in coronal holes.  The
map is based on line of sight intensities observed in the corona above
the limb and so they give only an approximation of the spatial extent
of structures in the longitudinal direction.
